Which of the following is NOT one of the top three factors affecting the level of injury from electric shock?

The correct response identifies voltage as not being one of the top three determining factors in the level of injury from electric shock. The three critical factors that significantly influence the severity of injury are generally recognized as path, current, and time.

Path refers to the route electricity takes through the body; different paths can lead to varying degrees of harm. For example, a shock passing through the heart can be much more lethal than one that does not affect vital organs.

Current is pivotal because the amount of current flowing through the body is what causes damage. Higher currents can disrupt bodily functions, leading to more severe injuries or fatal outcomes.

Time is also crucial, as the duration of exposure to electric current impacts the extent of injury. A brief exposure may result in minimal damage, while a prolonged contact can lead to severe injuries or death.

While voltage is indeed an important factor in the context of electrical safety, it does not directly correlate with the level of injury in the same manner as the other factors mentioned. High voltage can lead to high current flow under the right conditions, but ultimately it is the current that causes the injury and the path taken and duration that determine its severity.
